Fully automatic winding machine functions are more and more comprehensive：

With the development of the electronics industry, the demand for coils is increasing and there are more and more varieties, ranging from large power transformers, generator windings to miniature coils for charging, coils for energy-saving lamps, and various types of electrical equipment. used coil. The use of coils has popularized all aspects of human daily necessities, which has brought new development opportunities for the fully automatic winding machine manufacturing industry. Among the various automatic winding machines used, there are the earliest manual windings, and there are also mechanical automatic winding machines and automatic winding machines in the form of mechatronics control. In recent years, the manufacturing level of domestic automatic winding machines and the manufacturing level of imported automatic winding machines have formed a fully automatic, multi-functional and efficient automatic production capacity. From coil production on-line, feeder, end winding to coil winding and off-line, the process is automated. From the point of view of the control form of the automatic winding machine, it has developed from a single open-loop control to a closed-loop control using a DC servo system and an AC servo system. Coil to multi-axis winding of multiple coils at the same time a series of products. In the form of the county-level mechanism, according to the different structure of the iron core or skeleton of the coil to be wound, a shuttle-type automatic winding machine has been developed to adapt to the coil of the ring or other closed iron core or skeleton. In short, the automatic winding machine as a coil production equipment has become more and more popular and its functions are more and more comprehensive.

The hollow electromagnetic coil high-speed automatic winding machine can wind transmission coils, speaker coils, antenna coils and various general-purpose coils without skeleton. The equipment has reliable performance, high speed and high efficiency, and a high degree of automation, which is suitable for mass production in coil manufacturing.

Generally, the ordinary automatic winding machine adopts a small PLC with built-in pulse function. The speed of the winding shaft encoder is output to the built-in high-speed input point of the PLC, and the speed ratio of the winding shaft and the winding shaft is simply synchronized. This method is affected by the PLC operation. , the synchronization accuracy is poor, the calculation amount is large, and the CPU processing time is long, so there will be problems such as uneven winding, accumulation, collapse, etc., which seriously affect the quality of the finished winding product. For example, the PLC counts the winding shaft encoder at high speed. , when the count value is reached, use the interrupt method to control the reverse winding of the cable shaft motor, but due to the influence of the CPU operation processing time, there will be lag and errors, and the winding requirements can be basically met at low speeds, but for high-speed windings When the multi-layer coil is used, the coil end surface will be uneven, and the quality of the finished product will be reduced.

The special motion control PLC for high-speed automatic winding machine of hollow electromagnetic coil adopts high-speed dual-CPU structure, and uses independent CPU to process motion control algorithm, which can well realize various motion trajectory control, logical action control, linear/arc insertion Compensation control, etc. In the high-speed automatic winding machine, the electronic cam function of the 20PM motion controller is used to solve the problems of uneven winding, accumulation and unevenness in the winding reversal.
